Application filed May 5, 1902. Serial No. 105,993. (No model.)

5 useful Improvements in Dump-Wagons, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to improvements in dump-wagons, having moreparticular reference to that class in which the bottom walls of thedump-box is composed of laterallyswinging bottom doors.

One of the objects of this invention is to enable the operator to drawthe opposite ends of the meeting edges of the doors to their closedposition with a single cable, whereby any inequality in the movement ofthe doors may be readily taken up, so that one end of the doors may beclosed astightly as the other.

Another object is to provide a gravity-detent in conjunction with aratchet on the winding-drum for the cable for holding the swingingbottom doors in their closed posianother object is to provide a suitablestop on the doors adapted to engage the felly of the wheel for limitingthe outward swing of the doors.

To this end the invention consists in the combination,construction, andarrangement of the parts of a dump-wagon, as hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, Figures 1 and 2 are respectively side andrear elevations of a dump-wagon embodying the various features of myinvention, portions of the side of the doors being shown in a closedposition in Fig.

I 1 and in their open position in 2. Fig. 3

is an enlarged longitudinal section through the front portion of theframe and dump-box, showing particularly the fifth-wheel and kingboltconnection, the means for rotating the winding-drum, and also the meansfor holding the drum and the doors connected thereto in their operativepositions. Fig. 4 is a top plan of the parts seen in Fig. 1, except thatthe fifth-wheel is omitted. Fig. 5 is a perspective view of the detacheddoors and the cable for closing the same. Fig. 6 is a detail viewof thedoor-stop shown in engagement withthe felly and the door of one of therear wheels. Fig. 7 is a detail view of the sliding plate for theking-bolt and a fragmentary portion of the platform upon which saidslide-plate moves.

Similar reference characters indicate corresponding parts in all theviews.

In the drawings I have shown a dumpwagon consisting of front and rearaxles 1 and 2, a wagon body or frame having a dumpbox 3, a drum 4, andcable 5, connected to operate the doors of the dump-box, a detent 6, andsuitable mechanism 7, controlled by the operator for releasing thedetent, and means for rotating the drum.

Mounted upon the axles l and 2 are suitable front and rear wheels 1 and2', the front axle being provided with the usual hounds 8 andfifth-wheel section 9, and is also provided with an aperturelO toreceive the lower end of a king-bolt 11.

lhe forward end of the main body of the vehicle is provided with theusual fifth-wheel section 12 and a plat-form l3,having an elongatedaperture 14, which receives the upper end of the king-bolt l1. Movableupon this platform 13 is a sliding plate 15, having a con tral aperture16 and an elongated slot 17 the aperture 16 receiving the extreme upperend of the king-bolt and closely fitting the same, and the slots 17receive suitable bolts or screws 18, which permit the plate to be movedendwise transversely of the body as the kingbolt is rocked by thetilting movement of the axle when the wheels are passed over unevensurfaces. This arrangement of the king-bolt, with its lower end securedto the axle and its upper end playing in the elongated opening 14 andsecured to the sliding plate 15, pre vents the pounding and consequentwearing away of the platform 13 and at the same time firmly holds theforward end of the body in proper relative position upon the hounds.

The dump-box 3 is provided with side, front, and rear walls 19, 20, and21 and with a bottom wall composed of separate sections or doors 22 and23, which are hinged at their outer longitudinal edges to the lowerlongitudinal edges of the sides 19 in such manner as to meet in a linesubstantially midway between the side walls 19 and to automaticallyswing outwardly toward the rear wheels by their own gravity during theoperation of discharging the contents of the box.

In order to limit the outward movement of the free edges of the doors 22and 23 and to prevent any injury thereto by contact with the wheels, Iprovide each of said doors with a suitable stop or wearing-plate 24,which are so arranged as to engage the tire or felly of the rear wheelin front of its axle. These stops 24 are usually formed of metal and aresecured to the outer faces of the doors by clamping-bolts or screws 25.

The doors 22 and 23 are hinged to the side walls 19 by any desired formof hinge, as straphinges 26, the corresponding hinge-sections beingsecured to the side walls and the other sections to the lower faces ofthe doors by screws or bolts. One of these side walls 19 is providedwith a pair of openings 27 in proximity to the adjacent ends of thefront and rear end walls and 21 for receiving rollers or sheaves 28,which are journaled in suitable bearings 29.

Journaled in a bracket 30, substantially midway between the oppositeends of the front wall, is an additional pair of rollers or sheaves 30,a similar pair of sheaves 31 being also journaled on abracket 31,secured to the outer face of the rear end wall 21 at substantially itscentral portion.

The forward ends of the meeting edges of the doors 22 and 23 areprovided with bearings 33 and 34 for receiving additional sheaves 35and36, the rear end of the door 23 being also provided with a bearing37, which receives a roller or sheave 3S, and the rear end of themeeting edge of the door 22 is provided with a suitable engaging member,as an eyelet or hook 39.

The means for elevating the doors to their closed position consists,essentially, of the drum 4, cable 5, and a hand-lever 40, provided witha pawl 41 for engaging the ratchet 42, secured to the drum. This drum isjournaled at its opposite ends in open-sided brackets 43, which aresecured to the inner faces of the side walls 19 in front of the end wall20. This being the usual mounting for the drum, it is believed to beunnecessary to further describe the same.

The ratchet 42 is preferably secured at one end of the drum, and theoperating member is loosely jonrnaled on the drum in proximity to theratchet-Wheel, and the pawl 41 is pivotally mounted upon the lever 40 insuch manner that when the lever is elevated to a vertical position thepawl will drop antomatically into engagement with one of the teeth ofthe ratchet-wheel, and as the lever is then rocked forwardly the drum 4will be rotated in the same direction to wind the cable thereon. Thiscable and the method of connecting the same to the doors form one of theessential features of my invention, as it is believed to be new tooperate both doors from both ends with a single cable. As seen in thedrawings, Figs. 1 and 5, one end of this cable, the forward end,is'secured to the drum 4 by any desired fastening means and is thenpassed around the sheave 35 and over one of the sheaves 30 and iscontinued around the sheave 36, over the other sheave 30, and is thenpassed around the sheaves 28 at the outside of the box and is continuedover one of the sheaves 31 around the sheave or roller 38 at the end ofthe door 23 opposite to the roller 36, after which it is continued overthe other roller or sheave 30 on the rear end wall, and its opposite endis then secured to the eyelet 39 at the end of the door 22 opposite tothe sheave 35. This forms a continuous connection from the drum to theopposite ends of the meeting edges of the doors and permits the doors tobe elevated or drawn to their closed position firmly against the loweredges of the end walls 20 and 21. This arrangement of the cable andsheaves also acts as an equalizer to take up any inequality of movementof the opposite ends of the meeting edges of the doors. For instance, ifthe meeting ends at one edge of the door should be drawn to its closedposition before the other end has reached the limit of its movement thecon-- tinued winding of the cable upon the drum would force said otherend to full limit of its movement. This is an important feature of thisclass of dump-wagons, and it prevents any openings or cracks throughwhich the contents of the dump-box may sift.

Another important feature of myinvention is the means for controllingthe operation of the detent 6. This means preferably con-' sists of afoot-lever and a link 51, the lever 50 being pivoted at 52 to a bracket53, secured to one of the side walls 19, its forward end being providedwith a foot-engaging portion 54 and its rear end is connected to thelower end of the link 51, the opposite ends of said link being connectedto an extension 55 of the detent 6. The connection between the detent 6and the foot-lever 50 is so arranged that the gravity of the connectingparts antomatically forces the detent into engagement with the teeth ofthe ratchet, thereby obviating the use of any springs.

The operation of my invention will now be readily understood uponreference to the foregoing description and the accompanying drawings,and it will be noted that some change may be made in the manner ofconnecting the cable from the drum to the doors without departing fromthe spirit of my in- ICC vention. Therefore I do not limit myself to theprecise construction and arrangement shown and described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a dump-wagon, a dump-box having movable bottom walls or doors,sheaves senected to the other end of said other door and its oppositeend connected to the drum, and idlers supporting the intermediateportions of the cable for the purpose described.

2. Ina dump wagon, the combination of a dump-box having front andrearand side walls, doors hinged to the lower edges of the side wallsand having their free edges meetingf substantially midway between theside walls, bearings secured to the opposite ends of the meeting edgesof the doors, a pair of sheaves secured to each of thefront and rear endwalls, additional sheaves at the ends of said end wall, a drum, and acable passed around said sheaves and having one end connected to thedrum and its other end engaged with the bearings at the doors.

3. In a dump-wagon, a dump-box having a bottom wall formed of sectionshinged to the side walls of the box, each of said sections beingprovided with a wearing-plate adapted to engage a portion of the wheelsfor the purpose described.

In witness whereof I have hereunto set my hand this 2d day of May, 1902.
